Go back to your spreadsheet for problem 2.10. Compute the entropy for
each macrostate. What is the most probable macrostate and what is its
entropy? What about least probable? Also compute the entropy over
long time scales, assuming that all microstates are accessible.
(Neglect the factor of Boltzmann's constant in the definition of
entropy.) Plot Entropy as a function of macrostate. How does it
complare to the graph of multiplicity? Does it behave as expected?

**Monday 4/8/13** - Read Planetary Science chapter and do: 3.5, 3.11,, and problem 5.40 from Schroeder, and

- An astronomer measured the brightness of Jupiter at 17.6 terahertz to be 9.2e12 Jy (Actually, no one would use Jansky's at this frequency, but I wanted to make you do an extra conversion). What is the brightness temperature? What is the peak frequency for this temperature? What brightness do you expect to measure at this frequency?
- On a slowly rotating body, which area would be warmer at local midnight, area A with a higher thermal inertia or area B with a lower thermal inertia? Which area would be warmer at noon? Assume both areas are at the same latitude and there is no internal heating.
- Can the same volcano erupt a basaltic lava one year and andesitc later? Can the same volcano produce both granite and basalt? Explain.

**Wednesday 4/10/13** - Write a short paper summarizing what you learned this semester (~2 pages) OR discuss the goals list on the class syllabus (Do you agree with the list? What would you add? What would you remove?)

**Friday 4/12/13** - No class
